/* Dev console (dark, monospace, terminal accents)
 *
 * Mobile-first (docs/adr/0001). Unqueried rules are the mobile tier (320px up,
 * 16px gutters); larger tiers only add, via min-width queries:
 *   tablet   40em
 *   desktop  60em
 * Body text, like the home page, spans the chrome width, which stops at 1080px. Sizes scale with
 * clamp(), so breakpoints only change layout.
